v5` claims. (onse-22) This invention remiten.x to innerscies `of-tnat type wherein the inseam receiving ribinclucies a lip formed by inwardly. channelingabout the edge of at least the forepart of #an innersole blank, the lip being turned inwardlyandreinforced by one ormore layers or strips cemented in position, an inner layer-orvfstrip-.being folded back on itself. It is highly desirable yinfsuch constructions that the rib be inclined sharply inwardly at least duringr the placing-I of the inseam fasteners.

It is an object f the present invention` to'pro. vide a construction and methodof making by which Ithis sharp inward inclination of the `rib is assured. This is done in .accordance with' this invention by employing for the inner reinforcing strip a strip coated on one face with a cement for securing it to the top face of the blank and to so fold the strip that a portion ofl the coated face secures the strip in the desired position, this strip holding the lip in position;

For a. more complete understanding of this invention, reference may be had to the laccompanying drawings, inwhich Figure 1 is a perspective view. of an innersole constructed in accordance with and embodying the invention.

Figure 2 is a detail' sectional view on 1line-2'2 of Figure 1. i

Figure 3 is a perspective view showing the folding of a cement coated strip andv itsapplikholds the stitching rib in inwardly inclined po-V cation to a. channeled sole blank and the folding back of the channel lip against` the strip.

Figures 4, 5 and 6- are detailhsectional views on correspondingly numbered section. lines of Figure Referring to the drawings. at I is shown an innersole blank having a marginal inwardly directed channel cut around at least fthe -forepart` and preferably as shown extending 4also through the shank 'of the blank though, if desired, it might also be extendedv around the heel. Thischanneling operation forms a lip -2a'on one face and a feather 3 beneath the lip. There is then applied to the lip face of theblank and .substantially coextensive in length therewith, a-re-,i inforcing strip of sheet material I. As-shown best in Figures 2, 5 and 6. this str-ipl is preferably folded on itself longitudinallyat 5gto'form a double layer comprising an inwardly turnedv v portion 6 overlying a portion 1 which extends preferably inwardly of the portion 6 where it forms a single layer Svwhichfis cementedto the V lip face of the blank I. This folding or convoluting of the strip 4 may -be accomplished as it `ie'beingfed to the face of theblank as'shown in Figure 3 where the strip is vshown as passing y'through the folder-F. yPreferably]the strip is convoluted so that a marginal portion `9', of the upper layers is turned inwardly between the layersvri and 1. yCommonly this. strip material is coated on one face with a suitable adhesive, thisfacebeing the outer face of the convoluted portion so ythat it is `on the side confronting the face of the blank. This also brings-the cement coated face of the portion S'against the uncoatcd upper'face of the portion-Bxso .that when the partsare pressed together` the inner edge portion of `the outer convolution l is cemented to thesingle-H layer portion 8. This cementv attachment sition duringh the placing of inseam stitches, after which it is` not important that this inward inclination be retained, snee the remaining portion of the innersole lip formed by the portions 6 and .9 is removed by the inseaming 'trimming operation.l

thencomprises a portionV of the reinforcing strip IlL'the lip 2, and the upper layer 6 with its inturnedmarginal convolution 9 of the inner strip 4.

Thisapplication is, a continuation-impart of my application, Serial No. 531,758, filed April 19, 1944,l for Innersole and method ofmaking the same. l

From the foregoing description of an embodiment of. this invention, it will be evident to those skilled in the art that various changes and modifications might be made without departing from its spirit or scope.

I'claim:

1. The method of making an innersole, which comprises folding' a strip of sheet material ad- `hesively coated on one face lengthwise on itself in agpair'of convolutions and with the coated face outwardly tothus bring an in-turned edge `face of saidstrip with its coated face against the uncoated face of the outer convolution which extends therebeyond, cementing said folded strip The strip is cemented to the blank with its face outwardly to thus bring an in-turned edge face of said strip with its coated face against the uncoated face of the outer convolution which extends therebeyond, cementing said folded stripA 4. The method of making an innersole, which comprises folding a strip of sheet material lengthwise to form a pair of layers and with the margin of one layer of said material turned inwardly between said layers and cemented to the other of said layers, cementing said folded strip to one face of an innersole blank with the fold line between said layers facing the edge of said blank, turning inwardly and cementing the marginal lip oi said bank formed by an inwardly directed marginal channel about said blank to the outer face with said outer convolution inwardly facing, to

one face of an innersole blank inwardly from its edge, said blank having a marginal channel deiining a lip on the face to which said strip is cemented, folding said lip inwardly and cementing it to the outer face of the convoluted portion of said strip,` and cementing a strip of sheet material to the outer face of said lip and against the marginal feather outwardly of said lip.

3. The method of making an innersole. which comprises folding a strip of sheet material length wise to form a pair of layers and with the margin of one layer of said material turned inwardly between said layers and cemented to the other of said layers, cementing said folded strip to one face of an inner sole blank with the fold line between said layers facing the edge of said blank, and turning inwardly and cementing the marginal lip of said blank formed by an inwardly directed marginal channel about said blank to the outer face of said one layer.

of said one layer, and cementing a flat strip of `sheet material to the outer face of said lip and to the adjacent face of the marginal feather of the iinnerso'leoutwardly of said lip.

5. An innersole comprising a blank channeled inwardly about its margin to form a marginal lip and a feather, said lip being turned inwardly and cemented to a double portion oi a convoluted strip ofA sheet material, the inner convolution of said material being cemented to an outer convolution thereof, and a layer of strip material cemented to the outer face of said lip and to the channel face of said feather.
